What are the three types of Research Design?
|
Exploratory, Descriptive, Causal
|
|
Research Objective: To gain background information, clarify problems and hypotheses.
- Unstructured |
Exploratory
|
|
To describe and measure marketing phenomena at a point in time
|
Descriptive
|
|
To determine causality (if-then statements)
-experiments |
Causal
|
|
-Secondary data analysis
-Case analysis -Focus Groups |
Exploratory research methods
|
|
measure units from a sample of the population at only one point in time
(furniture survey) |
cross-sectional descriptive
|
|
repeatedly measure the same sample units of a population over time
(sexual abuse survey) |
longitudinal studies
|
|
use data to gain insights into changes in consumers' purchases, attitudes, etc.
|
continuous panels
|
|
ask panel members the same questions on each panel measurement
|
continuous panels
|
|
variable that the researcher has complete control over
|
independent
|
|
observing behavior as it occurs
|
direct observation
|
|
observing the effects of results of the behavior rather than the behavior itself
|
indirect observation
|
|
subject is unaware that they are being observed
|
disguised observation
|
|
repondent is aware of the observation
|
undisguised observation
|
|
researcher identifies beforehand which behaviors are to be observed and recorded
|
structured observation
|
|
no restriction is places on what the observer would note: all behavior is monitored
|
unstructured observation
|
|
-small group of people
-unstructured -spontaneous discussion -generate ideas and basic needs |
focus group
|
|
6-12 people
60-90 minutes |
size of focus group
|
|
strangers who share homogenous characteristics
|
who should be included in a focus group
|
|
-generate fresh ideas
-allow clients to observe their participants -easy access to special respondent groups - directed at understanding a wide variety of issues |
pros of focus groups
|
|
-Representativesness of participants
-interpretation sometimes difficult |
Possible errors of focus groups
|
|
Should not be used when the reasearch objective is to predict a specific number based upon sample data
|
when should you not use a focus group
|
|
participants are placed in simulated activities in the hopes taht they will divulge things about themselves that they might not reveal under direct questioning
ex: word association, role playing, etc. |
Projective technique
|
|
set of probing questions posed one-on-one to a subject to gain an idea of what the subject thinks about something or why they behave a certain way
|
depth interveiw
|
|
placing a person ion a decision-making situation and asking him or her to verbalize everything they consider when making a decision
|
protocol analysis
|
|
descriptive study of a group
|
ethnographic research
|
|
monitoring a respondent's involuntary responses to marketing stimuli via the use of electrodes and equipment
|
physiological measurments
|
|
Physically verifiable property
|
objective
|
|
mental construct
|
subjective property
|
|
Description, order, distance
|
three types of scale descriptors
|
|
the use of a label to stand for each unit on the scale
ex: male, female |
description
|
|
relative sizes of hte descriptors are known allowing us to say one is greater/less than the other
|
order
|
|
differences between the descriptors are known
ex: $1 difference between $4 and $5 |
distance
|
|
Nominal, ordinal, interval, ratio
|
levels of measurement of scale
|
|
those that only use labels
|
nominal
|
|
those with which the researcher can rank-order the respondnets or responses
|
ordinal
|
|
those in which the distance between each descriptor is equal
|
interval
|
|
ones in which a true zero exists
-most descriptive, exact numbers |
ratio
|
|
asked how much you agree or disagree
|
likert scale
|
|
value and personality traits of people as reflected in thier unique activities, ect.
|
life-style inventory
|
|
series of bipolar adjectives with the purpose of measuring brand evaluation
|
semantiv differential scale
|
|
respondent responds in the same or similar manner to an identical measure
|
reliability
|
|
accuracy of responses to a meausure
|
validity
|
|
only perfectly accurate sample
|
census
|
|
error
|
probability sample will always have some
|
|
calculated and expressed as a %
|
probablility sample accuracy and error can be
|
|
representativeness and accuracy
|
sampling errors
|
|
Two bigs factors in determining sample size
|
cost, desired accuracy
|
|
Central tendency, variability
|
two sets of descriptive measures
|
|
most common response to a question
|
central tendency
|
|
used to reveal how similar the responses are
|
variability
|
|
mean, median (middle) and mode(most frequent)
|
measures of central tendency
|
|
frequency and percentage distribution, range(max min), standard deviation (degree of variative in bell shape)
|
measures of variablity
|
|
making a generalization about an entire class based upon observation
|
inference
|
|
stats are used to make estimates of population
|
statistical inference
|
|
parameter estimation, hypotheses testing, tests of sifnificant differences
|
three types of stat inference
|
|
using sample info to compute an interval that describes tha range of values a the population would take on
|
parameter estimation
|
